Title: Diverse Inter-Region Path Setup/Establishment

This memo describes a mechanism to establish end-to-end diverse or disjoint
label switched paths (LSPs) across multiple regions, as required for
inter-area and inter-AS traffic engineering. The mechanism relies on the
joint computation, in each region, of the LSP segments of the diversely
routed LSPs, thereby achieving the simplicity of the per-domain approach
with effectively no changes to the signaling protocols. This is achieved by
the use of a new RSVP- TE object, called the Associated Route Object or
ARO, which is defined in this document and used in the signaling messages
in support of the scheme.
